Patent EP-0118607-A3 (EP)
Title: Encapsulated measuring device
IPC: G01B5/00
Filed: 1983-12-02
Abstract: An encapsulated measuring system for measuring the relative position of two objects (such as the slide piece and bed of a processing machine) includes a housing which is connected with a first one of the two objects. This housing serves to mount a measuring scale which is scanned by a scanning unit connected to a second one of the two objects. In order to compensate for thermally induced length changes of the first object, the housing serves simultaneously as an expansion element for the scale and as an encapsulating element for the scale and the scanning unit. The housing is fastened at a first fastening point with the first object and at a second, spaced fastening point to the scale. The scale is arranged to be slightly shiftable with respect to the housing in the measuring direction by means of a suitable adhesive. Preferably, the housing provides a greater coefficient of thermal expansion than that of the first object and thermal expansion of the housing between the first and second fastening points serves to compensate for thermal expansion of the first object to which the housing is mounted.

Abstract: A bottel cap of the tear-off type, particularly an easy-to-­
open cap for wide mouth bottles, in which a central top wall 
which covers the top portion of the mouth of the bottle is 
connected to a lateral band which surrounds the opening of 
the neck of the bottle and is bent under the edge of the neck 
to grip the cap, and a tear-off tab, bounded by one or more 
score lines, extends from the top wall through the lateral 
band and an angular sealing is interposed between the 
mouth of the bottle and the top wall and the lateral band. The 
score line or lines are located approximately at the bound 
line between the top wall and the lateral band and the 
angular sealing is bonded to the innermost surface of the 
lateral band at a bond area outside the score line or lines, 
whereby, when the cap is broken by lifting the central top wall 
by means of the tear-off tab, the residual lateral band ap­
pears L shaped and the angular sealing is broken only at the 
tear tab.  
     The sealing can also be bonded to the top wall at an 
extension of the bond area, bounded by the score line or lines 
towards the lateral band, to make the breaking of the sealing 
itself along with the tear tab easier at the time the opening of 
the cap is started.

Title: Method and apparatus for compacting foundry moulding materials
IPC: B22C15/00
Filed: 1986-03-20
Abstract: Foundry molding material is poured or pneumatically infed into a mold frame arrangement containing at least one pattern, a molding frame and a filling frame. Subsequently, the foundry molding material is compacted by a compacting arrangement containing, for example, any one of a compressed-air surge compacting device, a combustion-force surge compacting device, a pressure compacting device, a vibrational compacting device or a combined pressure-and-vibrational compacting device. Also during such compacting operation at least the predominant portion of the foundry molding material contained in the filling frame is displaced into the molding frame. During such compacting operation a preselected expanding gas is infed into predetermined local regions of the foundry molding material while such material is being compacted. As a result, there are formed zones of reduced packing density in the foundry molding material. During the further compacting operation, but in any case at the end of such compacting operation, the zones of reduced packing density are eliminated and the packing density of such zones is at least approximately equalized with the packing density prevailing in the remaining zones of the foundry molding material.

Patent EP-0208972-A3 (EP)
IPC: C08G77/42
Filed: 1986-06-27
Abstract: Linear polysilane-siloxane copolymers having remarkable 
sensitivity to radiation have the general formula  
[(SiMe₂) m ] a [OSiMeR) n ]b  
wherein Me is a methyl group, R is lower alkyl or phenyl, m 
= 4 to about 30 inclusive, n = 1 to about 100 inclusive, a and b 
may each be 1 to 10 about inclusive, and a units alternate with 
b units. The copolymers of the invention may be in the form of 
oligomers, random copolymers where n = 1 to 9, block co­
polymers where n = 10 to 100, and mixed (random and block) 
copolymers. These copolymers may also be in the form of 
modified copolymers having reactive functional groups such 
as acrylate, methacrylate, vinyl or other unsaturated substitu­
tions. The copolymers may be produced by formation of a 
halogen terminated oligomer of a polysilane or polysilane-si­
loxane copolymer, followed by coupling the oligomers with 
themselves or with distinct higher molecular weight silanol 
terminated siloxane species. Depending upon their specific 
structures, the copolymers respond to electron beam or ultrav­
iolet radiation by depolymerizing, behaving as photoinitiators 
for acrylate polymerization or cross-linking.
